Pretty disgraceful, though the Koch Foundation claims it no longer tries to do that.   Any such interference violates core academic freedom values, which includes the right of the university to decide on faculty appointments based on discipline-specific standards, not the preferences of external donors.   I doubt the Koch Foundation gift to the law school at George Mason involved any such provisions, since the law school at George Mason is so far to the libertarian fringe that most of my libertarian colleagues would be on the left end of their faculty!
